Alesis SR-16

My current rythmbox (Yamaha RX-11) is quite limited; I really wanted something more flexible. I was lucky to purchase an Alesis SR-16 at a very good price. Not a lot of sounds (230, which is not so bad), but it's not a problem as I intend to use the S5000 as a sound generator. What I was really looking for is more patterns; the SR-16 has 400.
